The production line of sand making machine can break the widely distributed and abundant rocks in China into sand and stone that meet the standards of sand and stone, replace the use of natural sand and relieve the tension of sand and stone. The following is to introduce the process flow and equipment recommendation of sand production line.
I. Pretreatment
If limestone, bluestone, river pebbles, granite and other sand making materials contain too much soil and impurities, they can first be sorted out for debris that is not suitable for crushing, and debris such as waste wood and plastic can be removed to facilitate the next processing process. If necessary, magnetic separation of raw materials can also be carried out to remove scrap iron.
Two, raw material crushing
The vibration feeder will feed the raw material evenly into the coarse crushing equipment, the raw material for a level of crushing, according to the different hardness of processing raw materials, coarse crushing can choose jaw crusher, coarse breaking, particle size qualified materials from the conveying equipment transported to the fine crushing equipment for further crushing, do not meet the requirements of the return to the coarse breaking machine.
JC series jaw crusher: a section of crushing equipment, rough crushing of materials, simple structure, large output, small footprint, high crushing efficiency; JC series jaw crusher
GPY/HPY series cone crusher: two-stage crushing equipment, crushing of pebbles, granite, basalt and other materials with greater hardness, good wear resistance, long life, low production cost, energy saving and environmental protection, mostly used in large sand and stone factories;
PFQ series impact crusher: two-stage crushing equipment, for limestone, basalt, coal gangue and other materials with low hardness for fine crushing, low investment cost, adjustable particle size of finished material, good particle shape, small footprint.
Three, stone sand
The finely crushed stone can meet the feeding requirements of the sand making machine. At this time, the sand making machine is used to finely shape the material. The sand particle size is uniform after being treated by sand making machine.
PLS vertical impact type sand making machine: "stone hit stone, stone while the iron is hot" two broken pattern, stronger adaptability, high efficiency, intelligentize degree is high, operation is stable and reliable, with plastic function, the output of the application of granularity and the reasonable distribution, grain shape good, whole sealing is good, not easy to produce dust pollution, energy conservation and environmental protection.
Four, finished product screening
Most sand screening process will use circular vibrating screen, according to user demand, finished sand by vibrating screen processing, can be screened and graded into coarse sand, medium sand and fine sand.
Five, sand cleaning
In order to improve the quality of finished sand, especially in terms of cleanliness, special sand washing equipment can be configured after the sand making process to clean the sand.
DXS series bucket wheel sand washing machine /XL series spiral sand washing machine: At present, the most commonly used bucket wheel sand washing machine is a new type of sand washing equipment with relatively high efficiency. It is mainly used for washing, grading and dehydration of mechanical sand, stone powder, mountain sand and river sand.
